How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Ask before painting over external sealant
- Show decorators and builders where the movement joints are
- Act on the first splits you see
- Clear growth from the base of walls and joints
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.
External mastic in Smarden Bell: local notes
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you look after a building such as Smarden Primary School, its movement joints, gutters and trims need looking after like any other building’s. Rented homes near Headcorn station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Why act early in Smarden Bell
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. Older cottages and farmhouses around Smarden Bell can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before work begins.

Surface by surface
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. We size the backing rod to the gap.
Render joints
The face of render can be soft, so a sealant that stretches easily protects the edges. We prime where the product needs it.
Smarden Bell: your questions answered
Is Smarden Bell in your area for external mastic?
Yes. Our work covers London and the South East, and Smarden Bell is part of that. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear quote.
I let a flat near Headcorn station. Can you help?
Yes. We work for landlords and agents as well as householders. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we’ll send you a clear quote.
How long does external mastic last?
It depends on the exposure, the movement and the product. Sealant is a maintenance item, so check the joints once a year and renew it when it starts to fail.
Where are you based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
Can you match the colour of my brickwork?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We choose the closest to your brick or render so it doesn’t stand out.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Is it messy?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
How it works
Every visit runs the same way: we check the joints, protect the area around them, do the work and clear up. It normally takes a few hours to a few days, depending on the length of joint and the access. Somewhere as small as Smarden Bell, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- Tell us about any water getting in
- Clear items away from the joints we’re working on
- Where the joints are inside, avoid wetting them before we arrive

Advice
Signs you need external mastic in Smarden Bell
Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
People generally contact us when they notice one of these:
- Gaps where render, brick and frames meet
- Joints pointed up with cement by mistake
- Moss and dirt in joints with no sealant left
- Old sealant gone brittle and cracked
Homes close to Church of St Michael include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.
Before booking anyone

- How hidden problems are handled
- Whether you can choose the colour
- How much experience the applicator has
